HOOD AND SMOKE-PIPE FOR LOCOIVIOTIVE-ROUNDHOUSES.

Specification of Letters Patent.

ratented April 24, 1966.

Application filed May 8, 1905. Serial No. 259.4182.

To all whom it may con/:ern:

Be it known that I, EDWARD SPENCER PIPER, of the city of Toronto,in theProvince of Ontario, Canada, have invented certain new and usefulimprovements in Hoods and Smoke-Pipes for Locomotive-Roundhouses, ofwhich the following is a speciiication.

The object of my invention is to devise a convenient, simple, anddurable hood and smoke pipe for locomotive roundhouses and it consists,essentially, of a box supported within the roundhouse and having its endprovided with a door normally closing the end, but adapted to be movedby the smoke-pipes of a locomotive to permit the pipes to pass into orout of the hood, and of a smoke-pipe composed of a plurality of sectionsof some non-metallic fireproof substance connected by metal frames,substantially as hereinafter more specifically described and thendefinitely claimed.

Figurel is a side sectional elevation of my Fig. 2 is a improved hoodand smoke-pipecross-section of the hood. Fig. 3 is a perspective view ofthe smoke-pipe,partly broken away. Fig. 4 is a sectional detail showinga modification of the framing of the smokeripe ln the drawings likeletters of reference'indicate corresponding parts in the differentfigures.

Referring particularly to Figs. 1 and 2, A represents a portion of theroof of a locomotive-roundhouse. Under this roof is supported the hoodB, formed as a box or trough, open at each end and at the under side.The ends are normally closed by doors O, each door comprising twosections horizontally hinged together at the center of the door andpivoted on the hood at or near the u per sides ofthe doors. The weightof these c oors normally maintains them closed, shown on the right handin Fig. 1. The pressure of a locomotive smoke pipe will, however, openthem, as shown on the left hand in the same figure, and as soon as thesmokepipe has passed by the door will resume its normal position. Thegates, it will be seen,will also yield readily to permit the smoke-pipepassing out of the hood. By my arrangement l avoid all necessity forswinging or lowering the hood, which is a great saving of labor andtrouble, and at the same time avoids all possibility of the hoodbecoming injured or destroyed by a locomotive. The

top of the hood has an opening therein communicating with the interiorof the smokepipe D, which will be hereinafter more particularlydescribed. As it is desirable to be able to draw up the chimney thesmoke and gases which may accumulate under the roof A above the level ofthe lower edge of the hood,

l provide the hood with a series of openings E near its top, at one orboth sides. These openings are controlled by any suitable dampers. lnFig. 2 l show hinged dampers F. Cords G, suitably weighted and passinground guide-pulleys, serve normally to keep the dampers closed. Othercords H, passing round suitable guide-pulleys and secured to thedampers, serve as means vfor opening the I dampers when required.

The smoke-stack comprises a framing I, composed of vertical groovedmetal bars. These may be T-bars, as shown in Fig. 3, or double U-bars,as shown in Fig. a. These bars are secured to the base J in any suitablemanner and also to the top K. Into the grooves of the bars are slid aseries of sections or staves L, formed of some suitable noncorrosibleiireproof material, preferably nonmetallic. These sections may be ofwood, suitably fireproofed, of asbestos board, slate, tiles, wiredglass,or other equivalent materials. Bands or hoops M surround theoutside of the pipe and serve to maintain the parts in position. Thesebands are particularly necessary when the construction shown in Fig. 3is employed. The sections L are preferably tapered, so as to produce atapered pipe, as shown.

Tithin the chimney is located a suitable damper N, operated in anydesired manner.

A chimney-pipe constructed as described willbe easily built, fireproof,and durable. The sides of the hood are preferably constructed in muchthe same manner as the chimney-pipethat is, by a metal frame O withpanels P of non-corrosible tireproof material held therein.

Vhatl claim as my invention is- 1. In a device of the class described ahood open at its under side and provided at one end with a door normallytending to assume a closed position but adapted to be moved by thesmoke-stack of a locomotive to )e1-mit the stack to pass into or out ofthe hood, substantially as described.

2. In a device of the class described a hood open at its under side andprovided at one IOO IIO

top, substantially as describe 3. In a device of the class described ahood open at its under side and provided at one end with 'a doornormally tending to assume a closed position, but adapted to be moved bythe smoke-stack of a locomotive to permit the stack to pass into or outof the hood in combination With a smokeipe communicating With the top ofthe hoo substantially as described.

4. In a device of the class described a hood open at its under side andprovided at one end With a door normally tending to assume a closedposition but adapted to be moved by the smoke-stack of a locomotive topermit the stack to pass into or out of the hood, in combination with asmokei e communicating With the top of the hood Iboth the hood andsmoke-pipe being formed of sections of noncorrosible iireprooi materialconnected by metal framing, substantially as described.

5. In a device of the class described, a hood open at its under side androvided at one end With a door horizonta y hinged at or near its top onthe hood whereby it tends to maintain a closed position, but is adaptedto be moved by the smoke-stack of a locomotive to permit the stack toass into or out of the hood, substantially as escribed.

6. Ina device of the class described, a hood open at its under side andprovided at one end With a door formed in tWo parts horizontally hingedtogether, the upper part being pivoted on the hood so as to tend toassume a closed position but adapted to be moved by the smoke-stack of alocomotive to permit the stack to pass into and out of the hood,substantially as described.
